Salvages the closed PR #2010 (Mibayy's EVM multi-chain skill) and folds the
existing optional-skills/blockchain/base/ skill into it, so we ship one
unified EVM skill instead of two overlapping ones.
Pulled in from base/:
- 8 missing Base-specific tokens (AERO, DEGEN, TOSHI, BRETT, WELL,
cbETH, cbBTC, wstETH, rETH) added to KNOWN_TOKENS['base'] —
base/ had 11, evm/ only had 3 (USDC/DAI/WETH).
- L1 data-fee pitfall note for rollups (Base, Arbitrum, Optimism, zkSync).
- Batch-size chunking in rpc_batch (Base RPC caps batches at 10 calls
per JSON-RPC request; adding more known tokens tripped that limit
and broke 'wallet --chain base' with a 'list index out of range'
error). Ported the chunking pattern from base/_rpc_batch_chunk.
Latent bugs found and fixed while smoke-testing the merge:
- cmd_multichain and cmd_allowance both iterated KNOWN_TOKENS[chain]
with 'for contract, (symbol, _name) in known.items()' — but the dict
shape is {symbol: contract_str}, not {addr: (sym, name)}. This raised
'too many values to unpack (expected 2)' on every non-zero balance.
Now iterates as 'for symbol, contract in known.items()'.
- Input validation: added is_valid_address / is_valid_txhash /
require_address / require_txhash helpers and wired them into
cmd_wallet, cmd_tx, cmd_token, cmd_activity, cmd_allowance,
cmd_decode, cmd_contract, cmd_multichain. Fails fast with exit 2
on malformed input instead of burning an RPC round-trip on garbage.
Documentation:
- SKILL.md now flags that this skill supersedes optional-skills/blockchain/base.
- Pitfalls expanded for ENS (single-endpoint dependency on
ensideas.com), tx decoding (single-endpoint dependency on
4byte.directory), and rollup L1 fees.
- Regenerated website/docs/user-guide/skills/optional/blockchain/
blockchain-evm.md and removed the old blockchain-base.md page;
catalog updated.
Removed:
- optional-skills/blockchain/base/SKILL.md
- optional-skills/blockchain/base/scripts/base_client.py
- website/docs/user-guide/skills/optional/blockchain/blockchain-base.md
Smoke-tested live against Base mainnet: stats, price, token, wallet
(vitalik.eth — 3.12 ETH + 13.88 USDC + 4.23 DAI + 0.06 WETH on Base)
and allowance (ethereum, 7 unlimited approvals to Uniswap/Permit2).

- Implement tests for normalizing perpetual markets and DEXs.
- Validate JSON output for main commands including markets, candles, and review.
- Ensure environment variable resolution and dotenv file reading are covered.
- Test export functionality for market data with expected output structure.
Extends the Windows-gating work to the optional-skills/ tree. Every
SKILL.md that previously omitted the platforms: field now carries an
explicit declaration, which Hermes's loader (agent.skill_utils.
skill_matches_platform) honors to skip-load on incompatible OSes.

5 skills gated from Windows (platforms: [linux, macos]):
mlops/flash-attention - Flash Attention wheels are Linux-first; Windows
install requires building from source with CUDA
mlops/faiss - faiss-gpu has no Windows wheel; gate rather than
leak partial (faiss-cpu) support
mlops/nemo-curator - NVIDIA NeMo ecosystem has no first-class Windows path
mlops/slime - Megatron+SGLang RL stack is Linux-only in practice
mlops/whisper - openai-whisper + ffmpeg setup on Windows is
non-trivial; gate until Windows install stanza lands
Methodology: scanned every SKILL.md for Windows-hostile signals
(apt-get, brew, systemd, osascript, ptrace, X11 binaries, POSIX-only
Python APIs, Docker POSIX $(pwd) bind-mounts, explicit 'linux-only' /
'macos-only' text). 3 skills flagged as having hard signals on review:
docker-management and qdrant only had POSIX $(pwd) docker examples and
the tools themselves (Docker Desktop, Qdrant) run fine on Windows —
declared ALL. whisper had an apt/brew ffmpeg install path and nothing
else but the openai-whisper Windows install story is rough enough to
warrant gating.
Strict-over-lenient policy: when in doubt, gate. Easier to un-gate after
verified Windows support lands than to leak partial support that
manifests as mid-task failures for Windows users.
Enhancements to the Solana blockchain skill (PR #212 by gizdusum):
- CoinGecko price integration (free, no API key)
- Wallet shows tokens with USD values, sorted by value
- Token info includes price and market cap
- Transaction details show USD amounts for balance changes
- Whale detector shows USD alongside SOL amounts
- Stats includes SOL price and market cap
- New `price` command for quick lookups by symbol or mint
- Smart wallet output
- Tokens sorted by USD value (highest first)
- Default limit of 20 tokens (--limit N to adjust)
- Dust filtering (< $0.01 tokens hidden, count shown)
- --all flag to see everything
- --no-prices flag for fast RPC-only mode
- NFT summary (count + first 10)
- Portfolio total in USD
- Token name resolution
- 25+ well-known tokens mapped (SOL, USDC, BONK, JUP, etc.)
- CoinGecko fallback for unknown tokens
- Abbreviated mint addresses for unlabeled tokens
- Reliability
- Retry with exponential backoff on 429 rate-limit (RPC + CoinGecko)
- Graceful degradation when price data unavailable
- Capped API calls to respect CoinGecko free-tier limits
- Updated SKILL.md with all new capabilities and flags
Solana blockchain queries are a niche use case — not needed by every user.
